Water surface temperature (Wahweap Bay) on 5/26/2026: 73.0-78.0 F. Lake Elevation: 3,527.87 MSL (and rising). Note: Please be advised that each calendar year, Utah has requirements for motorized boats before launching at a Utah waterbody. Read the following: 

1. Register your vessel with your state’s Division of Motor Vehicles (or the equivalent in any
state/province for boat registration) — you will need your bow number to enroll in the
Utah AIS program.
2. Complete the annual DWR mussel-aware boater education course. Print out your proof of course completion or download it to your DWR Hunting and Fishing app.
3. Enroll your vessel in the Utah AIS Program. An annual fee per watercraft applies: $20 for
Utah residents and $25 for non-resident vessels.
4. A current-year AIS decal will be mailed to you; affix it to your boat with the instructions
enclosed in the mailer.
Important: You must have a professional decontamination completed before launching your
vessel in any Utah waterbody — regardless of season — if:
- You are entering Utah from another state.
- You have been at a mussel-infested water and not met the 30-day dry time required
for complex boats (vessels containing inboard motors, inboard/outboard motors,
ballast tanks, bilges, live wells, generators, AC units and any other raw water
systems).
